v Water chamber P3 of: the hot Well, where the lill path of the cooling Water is indicated by plain arrows. The path of the vapor on the other hand is indicated by barbed arrows. This vapor enters through he exhaust pipo L into the shell D,Aand the central series of the tubes lzl having the colder Water, the tendency of this vapor is to low inward to Ward the center el' said group oi tubes, Where the aqueous vapor is condensed, and the air and rareiied vapor flow upward and outward tl'irougjh the opening hetween the top of the shell l) and the hopper i', passingr upward to the pipe O, Where it is drawn oli by the vacuum pump, not shown. The tendency of the vapor te flow inward toward the een-- ter ol' the grou p oi tubes ifi' is augmented by the annular diaphragm, lll. The distilled Water drops down on 'the bottom oi the chamber D, and escapes through the sweet water tail pipe N,`lowing into the sweet grease is trapped olli, and the fresh water fed to the boilers through. the pipo R. The vacuum pipe 0 opens iut-o the part A oi the conde: ser near its highest part, and the drain pipes M and N lead from the hottorn of their resptwtive chambers. 'llhus the air 'remaining in the system is drawn oli" in a dry state, and the water, both the coolingy and the listillod water, `is allowed to .flow oil` through gravity. l't will. he seen that the apparatus hereinbefore described comprises 'a surface condenser located in the renter of an annular ict 'eoudenser, the saine cooling water being*r used for both. it will he noted that the vacuum isv the saule ou the inside as ou the ouiside of the tubes il', and therefore a leaky tuhc will have no efl'eet on the vacuum. Again,v the upper head l is free to rise or fall as the tubes eX- paud or contract, which motion is permitted hy the expansion joint ii, und `for this reason all the tubes can be mpanded into the tube heads like boiler tuiles', and there is no necessity for ierrules', thinihtis, stulling boxes, or the like1 such as are used in many surface condenser-s at present rnauufactured. it u ili be noted that no w pump is needed to ,fret the .vaier out of the condenser.

ivell loiowu, a surface condenser' re- .rpiirs uiore eooliup` rincer thor a Iiet condens r, .because the tubes are not as ell'eetive as rvhere the sten-in cornes in direct contact with the cooliupr water. i

My invention provides 'for a combination. of the tiro l'orius of the condenser, so that iuost of the actual condensation is effected in the tuhes, while the remainder dts froui the direct contact of the vapor .1- eooliug water, so that the h; l ".xf'lleii j the jet eoudeuseri time inost ot :mused und is :u ffiin in the l in power plants,l especially electric rail-vv way plants, Where the load varies Within Wide limits, il' a surf ace condenser alone he used, it must be very large and costly, in order to secure the requisite cooling' surface, but my idea is to arrange the surface condenser for the normal load, and let all the overloadsbe taken care of by the jet. The amount of the circulating Water can. be regu.-

lated to Whatever is needed 'by varyingr the s )eed of the circulating' pump. By having;

shell A suiheiently elevated, the Welllnown advantages ol the baronietric tube `iet condenser are secured, and at the-saine 'time by the herein described construction: the greater portion of the Water evaporated is separated out in the form of distilled water which is suitahle for use. over again in the boilers. lt will be notedA that the vacuum acting on the upper end of the outer ries o lvl tubes .il will `tend to suck water` down from the funnel lig and therefore this vacuuni -will assist the pump in foreing'the Water up through the pipe l.

rlhe herein described device is believed to he simple in `construction and econorn'xal und efiicient in operation.

lt will he ohvious that various changes Inight be nnide in the. herein described construction which could be used without de partingr frein the spirit of my invention.

Having thus described my invention, what .l claim and desire to secure by Letters Patent of the United States is l. A condenser comprising' an outer shell, an inner shell inclosed therein' and spaced therefrom, a surface condenser mounted in said inner shellfiind delivering the distilled Water to the inner Ishell and the cooling water to the outer shell, an exhaust pipe opening into the inner shellfa suction. pipe connected to the top' of the outer shell, a tail pipe for the cooling' water connected to the hottorn of the outer shell, and atail. pipo for tue distilled i iter connected to thin bottorn` oi the inner ll, suliistiuitially as (,leserihed.
